Hi Terry, The current V8 Supercar control tyre is a Dunlop 280/680 R17, whereas up til last year it was a Bridgestone 285/40 R17. Does this illustrate your point on how sizes are quoted differently, but overall the same info? As I take it the Dunlop tyre spec is quoting: Width/Tyre_dia-Construction-Wheel_dia While the Bridgestone is quoted as: Width/Aspect_ratio-Construction-Wheel_dia
